Trade school did not work for everyone. The trades still need people.

Mettle exists because the existing options for apprenticeship instruction are either a community college schedule your techs cannot keep, or a licensed textbook stack with a login screen and a per seat publisher fee.

Brian Norton built Mettle after years running both sides of the problem. He holds Virginia master licenses in HVAC, plumbing, and gas fitting. He works in commercial mechanical contracting, serves as the lead licensed instructor on a DOLI approved in house Related Technical Instruction program, and has spent years building online training for licensed tradespeople, with hundreds of techs through his continuing education courses.

The Mettle curriculum is written from scratch: every lesson, every quiz, every lab sheet. That matters for two reasons. The content stays current (A2L refrigerants and the modern code environment are the baseline, not an addendum), and there is no publisher license inflating your seat price.

The name comes from the old word for what the trades actually test: mettle, proven skill and nerve under pressure. Forge your future in the trades.
